Serial number unavailable in about this mac

serial number unavailable in about this mac

" Yosemite Development Build"...." iMessage and other processes which require the internal serial # arent functioning "
Uhhh so a beta version of Yosemite? Some of those other processes have not been working even with the latest version of Yosemite.
The serial number should still be on the bottom. Even if the bottom is changed the Apple standard operating procedure is to write the serial number on the inside of the new bottom case.
" arent functioning because of this issue"
So it's asking you for the serial number?

  • G5 Serial Number not in "about this mac"

    Am I crazy or is the serial number usually there when clicking on Version/Build. I thought the third thing it showed was the serial number for the machine. The only thing I can think of is that when I had my logic board replaced something got messed up. Or maybe its something else.
    Anyone?

    The serial number is stored on the mother board, so replacing it would cause the loss of serial number. There probably is a way of setting it through Open Firmware with a special password, but I don't know if normal Apple repair places can do it. You could try calling the place that did the repair.

  • HT1750 What about TWO different numbers in MacOs (about this mac window) and on the bottom of the foot of the iMac ???

    What about TWO different serial numbers in macOs (about this mac window) and on the foot of the mac. This mac was not purchased as a refurbished nor has been sent for servicing on any time since purchasing...
    The one in MacOs is answering : "This is not a valid Apple Product serial number" when i try to check the iMac 1TB Seagate Hard Drive Replacement Program...

    You will need to check with Apple - might be a good idea to take it to a Genius Bar so they can see it for themselves (and the diagnosis is free).

  • Why is my MBP serial number and model year no longer displayed in "about this mac" (have NOT replaced logic board)?

    I have not replaced or manipulated the logic board (or any other hardware) on my mid-2012 13 inch MBP. Under the "about this mac" tab, the serial number is no longer displayed (it now states "unavailable") and the model year is also no longer displayed. I understand that I can find the serial number and model year several other ways, I am seeking to determine why this happened and if it could indicate further problems.
    Has anyone else experienced this?
    Thank you in advance for any help or insight.

    Man oh man. What a day. New symptoms again!
    Lets start with the MBP dying in its sleep. I closed my MBP and left it for a few hours to come back to find it completely dead. Looked into this issue and with the help of the activity monitor cleaned up some things, turned off some sharing settings, got rid of some extensions, etc. Seems to have solved this issue.
    Later on, I picked up my MBP while it was on with my left hand and the same display (horizontal lines), freeze, auto shutdown happened. Out of curiosity I tried to recreate the symptom. Sure enough, pressing (with little force) on the left side of the bottom case caused it to happen again. I researched this a bit and found several possible culprits (bad logic board, metallic sticker may cause shorts, bad RAM bank, google drive). The google drive one really surprised me, I removed google drive (worked for many people) and it did not fix the issue. A buddy had some good RAM for me to use today so I swapped it out and had the same issue. Decided to test the individual RAM banks and it turns out that the deepest bank must be faulty. Running with only one 4 gig stick in the outermost bank and the freeze, shutdown, beep issue is gone!
    So, it seems I have fixed the dying in sleep problem and have a temporary work-around for the bad RAM bank. The SN issue remains.
    I am going to try to find out what could make a RAM bank be faulty and if there is a way to repair it.
    What are the chances that all this happens as soon as I try to find out why the SN is unavailable??
    Below is the thread that I found interesting and useful.

    Serial number? I have a MacBook Air (mid 2011). When I go into about this Mac or any of the other ways to look up the serial #,all it says for serial number is systemserial#. Is there a way to fix this?

  • About This Mac doesn't display system serial number!

    Hello. I've had this for a couple of months now and it wasn't up to now that it really started worrying me.
    Just a month after I bought my MacBook, I had to send it in for repairs (logic board fried... in one month!) and after I received it, I noticed something strange. When I open  > About This Mac and look for my serial number... it just... doesn't show any. It shows either SystemSerumb or SystemSerialNumb. Why? How? What?
    How can I write down my computer's serial number as it's supposed to be written? I know the number: I have it on the laptop's box and "under" the battery, so I won't write it wrong...
    Help!

    There is no need to be concerned as software does not ask for serial numbers.
    Software may look at existing hardware as CPU type or RAM or Disk space as well as OS version, previous installation, possible registration, but not the serial number.
    Technically, a serial number is more a software designation of the hardware, not hardware itself.

  • I looked up serial number in About This Mac and Support site says it isn't

    I can't find my Apple Care plan or read the bottom of the computer but I looked up the serial number on my iMac under About This Mac. I copied and pasted it into the box to get a call for technical support and I get a message saying it is not the right number. Now what? How can I call them to get support without the number?

    A valid Apple product serial number is eleven characters long, does not contain the letters I or O—though the numerals 1 and 0 are valid characters—contains the numeral 0 though 9 in the third position and the numeric string 01 through 52 in the fourth and fifth positions.
    On your model, it's found screened beneath a barcode on the underside of your foot, or can be found as you were instructed using About This Mac or using the System Profiler application. If your logic board has been replaced and is not the original unit installed at the time of manufacture, your logic board may not have the serial number embedded in firmware. In that case, it is not available to display using the About This Mac dialog or the System Profile application.
    The most reliable source of such information is typically the number screened on, inscribed or affixed by label to your Apple product.

  • Serial Number in About This Mac and System Profiler says "System Serial#"

    I recently had my hard drive and motherboard replaced under warranty.
    I wanted to check the expiration of my warranty so I could buy AppleCare before my year is up. I went first to About This Mac, and then to System Profiler - both of them say my Serial Number is "System Serial#" - any ideas on how to get my real serial number displayed?

    How strange! I'm not sure if this will show anything different, but you can also try to get the serial number via Terminal. Just open the Terminal application and copy in this command:
    ioreg -l | grep IOPlatformSerialNumber

  • About this Mac won't show serial number. What then?

    I have an iMac running Mavericks where "About this Mac" won't show the serial number. I checked the "System Report" and no serial number there either. What is causing this? Guess I have to look at the physical number.

    Was your logic board or hard drive replaced? In my case, the tech forgot to re-associate the logic board with my serial number and I also had none showing. He had to come back with a special tool to be connected to a particular Apple site and input it manually (fortunately, I had made a record of it).
    If there was a repair/replacement, call Apple and/or take it to your nearest Genius Bar so they can take care of it. FWIW, it should also be visible on the bottom of the iMac stand, so take a look (after you shut down the Mac and unplug it) and copy it for future reference.

  • HT1529 iphone:  where do I find "about this mac" so I can find my serial number ? ? ? ?

    1. Choose a Community: 
          I don't know what any of these are - I just want a simple answer !
    2.  iPhone:  I can't even find the place that I can find "about my MAC" ? ? ? ?
    3.  iphone:  and I need to find that page in order to find my serial nuimber.
    4.  so I'm totally lost !

    I'm confused, do you want the serial no for a Mac ('About this Mac') or about your iPhone? If the former, the answer is on the page you came from:

    Until last July, the model identifier on every Intel Mac would tell you exact minimum and maximum expansion in terms of RAM, retail operating system, and any system specific required firmware updates, video and audio expansion capabilities, and patches for Wifi available.  The serial number is only of consequence if you wish to date a Mac down to the week.  This can help in determining system specific disks, available warranty, and exchange/repair program eligibility.  Outside of that the year and month can usually be narrowed down to a six month period with model identifier alone on all except MacPros.  So my question is, is it really that relevant for your needs?

  • When I click "about this mac" to check on my storage, I get a number of different sections music, movies, etc. but also I get a section called backups, where can I find the files in this section?

    When I click "about this mac" to check on my storage, I get a number of different sections music, movies, etc. but also I get a section called backups, where can I find the files in this section?

    Welcome to Apple Support Communities
    All the storage in "Backups" is taken up by local snapshots, which are made automatically in all MacBooks, MacBooks Pro and MacBooks Air with OS X Lion or newer and Time Machine turned on.
    See > http://pondini.org/TM/30.html I recommend you to leave them there, because they will be removed automatically. However, if you want, you can disable or remove them manually if you want, even if there's no reason to do this. Have a look at the link above for more information

  • Anyone - that "About this MAC" only gives the OS X Version Number and not the Name?

    Is anyone else - that "About this MAC" only gives the OS X Version Number and doesn't also give out the Name?
    *** version is Mountain Lion? Snow Leopard? Yosemite?? And how hard would it be to use the name AND version number when they refer to a product?
    So What Do I have with 10.8.5 ?
    PS [as I use this site for the first, I am glad to see for the first time ANYWHERE that the drop down box lists the OS X by name and number. APPLE, PLEASE DO THAT EVERYWHERE!

    A google search would have yielded the answer
    10.8 is Mountain Lion.

  • Emac processing SLOW...wheel spins even when trying to open "about this mac"

    this is a new to me mac. I have only had it about 5 days.
    running 10.5.8.  1.42g 512 160g w/superdrive
    It runs slow most of the time. when I am connected to the internet it seems ok, but when running or trying to open things like itunes, system preferences, system profiler and other applications it keeps that annoying spinning wheel going for minutes.  I have even had to just shut it off and start it back up again by pressing the button.  also, when I put in a cd or dvd it takes forever to read it. and the drawer doesn't want to open readily.
    my other mac running 10.4.11 on 800mhz 512 80g doesn't have this trouble at all. I was thinking I was upgrading. 
    I tried to do repair permissions and that was taking forever, so I stopped it.
    I know I will get some smirks by this, but I do not have the start up disks. I purchased this used without the disks.
    I did look up some other posts about this, but wondered if there were some more suggestions without downloading anything.
    any help would be appreciated.
    thanks! Kelli

    Hi Kelli,
    10.5 needs twice as much Memory as 110.4 does, as wel it's far more demanding of the Video card & Hard Drive.
    These are "Minimums" which never suffice for much...
    Tiger Requirements...
    To use Mac OS X 10.4 Tiger, your Macintosh needs:
        * A PowerPC G3, G4, or G5 processor
        * Built-in FireWire
        * At least 256 MB of RAM (I recommend 1GB minimum)
        * DVD drive (DVD-ROM), Combo (CD-RW/DVD-ROM) or SuperDrive (DVD-R) for installation
        * At least 3 GB of free disk space; 4 GB if you install the XCode 2 Developer Tools  (I recommend 20GB minimum)
    http://support.apple.com/kb/HT1514
    Leopard requirements/10.5.x...
        *  Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor
    minimum system requirements
        * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)
        * DVD drive for installation
        * 9GB of available disk space (I say 30GB at least)
    So we know more about it...
